I have this problem where it seems as if corona interprets my displacement map differently between frames. It’s popping and jittering. I have attached a 45F render to show what i mean.
The displacemnt map is under a filter shader, is that not cool? The render was done on a single machine so we can rule out different machines calculating the map differently.
Have you tried to decrease the Screen Size of the displacement (it is under "Render Settings / Corona / Performance Settings, the default is 2 pixels which might be too rough), although in your special case I would switch to World size and use an appropriate value there (depending on the real world size of your details).
This is a very interesting issue. In order to fix it, I’d say replace displacement with bump and use displacement only for low-frequency variation. But the question is why doesn’t displacement handle your input data correctly?
Edit: In any case, I’d be interested in seeing the scene, if it’s not a problem
Lowering the Screen size under solved it. Thanks Mike. At first i tried to do world size but got really weird results unless going really small, but going too small increased the displacement calculation to insane times.
@houska, still want to see project file? Shouldn’t be a problem. The project is still live but I can make a stripped down/simplified file and send it over if you are still interested.
I am glad the problem is solved. What were the parameters that helped you fix it? Was the screen size something unnaturally large when you were having trouble with the displacement?
